The machine of our invention is eSllQiZiall-y designed for the making o binding tape porn: prising a metal ribbon or strand, a padding and a padding backing strip interposed between the strand and the padding as is illustrated in Figs, 0 an 1 h p being desi nated enera ly by the numeral I, the metal strand or r bbon 3, the padding with the numeral sand the backing strip with the numeral .4. These parts are 5451* hesively secured together, the adhesiye connect:- mg the backing to the padding being indi teg at 5, the adhesive connecting the metal d to the backing being indicated at 5. These binding tapes are well adapted for use in bind: ing objects which have a finished suriace which it is desired to protect. While the backing strip is highly desirable where the padding is made up of multiply creped tissue, as in the embodiment illustrated, the padding may be of such material as to render the backing strip unnecessary; however as stated, the maehm 5$ designed to produce the particular structure 11,-

The metal strand or ribbon 2 is supplied from a reel i8 and passes over a machine stop switch l9 designed to stop the machine in the event the strand becomes exhausted. The electrical connected of these stop switches to the motor are not illustrated. The metal strand is passed through the straightener 26 and through a guide 21 into contacting engagement with the adhesive applying roller hesive 6 is applied to the underside of the strand. From this adhesive roller the strand is guided by the roller 23 into superimposed relation to the backing strip. The backing strip is guided by the roller 24 and the guide throat 25 into superimposed relation upon the padding as is best shown in Fig. 4.

The adhesive applying rollers are so spaced from the point of superimposing the strand and backing and padding that the adhesive has time to become suitably tacky. The superimposed strand, backing and padding are passed between feeding and pressure belts 26 and 21 which have parallel rearwardly traveling reaches 28 and. 29 respectively. These reaches engage and apply pressure to the superimposed parts holding them in their superimposed relation until the adhesive has had time to set. That is one reason for the machine illustrated being of considerable length. It should be understoodthat by using a more quickly setting adhesive the machine could be shortened. The feed belts, however, are desirable as they grip and convey the superimposed parts of the-strand without displacement particularly of the padding material which is desirably quite soft in order to fully protect the object to which the tape is applied.

The motor 30 is conventionally shown in Fig. 1. The belts are supported by the driving and supporting pulleys 32 and 33. The belt tighteners 34 are provided to maintain the desired tension on the belts. Sprocket and chain connections are illustrated for driving various parts but details of these are not important except as will be pointed out.

The feed and pressure belts draw the material from the supply rolls and advance it rearwardly to the cutter units designated generally by the numerals 35 and 36. The purpose of these cutter units is to sever the padding and backing at spaced points, the cuts being most clearly shown at 31 and 38 in Fig. 10. The purpose of these spaced cuts is to facilitate the removal of the portion 39 of the backing and padding from the strand 2 thereby exposing end portions 40 of the strand to facilitate tying or securing the ends of the strand together. This is ordinarily accomplished by overlapping the ends of the strand and crimping the lapped edges as is quite common practice with metal binding tapes, tools being available for such purposes. To facilitate the breaking of the strand at a predetermined point into individual tie lengths the strand is scored, as indicated at 4| (see Fig. 10), thereby making it practical to sever the strand by flexing at this point and avoiding the use of cutters, also enabling the individual ties being produced of the desired length.

The cutter units 35 and 36 comprise the rotary cutters 42 and 43 with coacting press rollers 44 and 45. Guides 46 are provided for each cutter unit. The cutter rollers are provided with cutter blades 41 which are suitably positioned so that they cut through the padding and backing and 22 by means of which the ad- 4 desirably have recesses 48 in their cutting edges to receive the strand 2 and thereby avoid the cutting thereof and the dulling of the blades. The rotary cutter 43 has a scoring blade 49 which corresponds in length approximately to the width of the strand 2 (see Fig. 9). This blade cuts a slit 50 in the central part of the padding and backing strip as shown in Fig. 9 and scores the metal strand as indicated at 4|.

The cutter rollers have driving connections comprising the sprocket chain 5| and suitable coacting sprockets, see Fig. 3. The press rollers 44 and 45 are mounted in adjustable bearings 52 which permits their adjustment to and from the cutter rollers. The cutter roller 42 is driven v through the sprocket chain 54 which is connected 'where they receive to the shaft 55 of the roller 42 through a one revolution clutch 56 (see Fig. 3). The details of this one revolution clutch are not illustrated. The clutch is engaged, however, by means of the clutch lever 51 which is actuated at timed in-. tervals by means of the tappet 58' on the chain 53. This chain 59 is made up of links 60which may be readily connected or disconnected so that the chain may be lengthened or shortened thereby timing the engagement of the tappet with the clutch control leverand controlling the length of the individual ties.

The chain 60 is trained over the driven sprocket 6|, the supporting sprocket 62 and the sprocket 63 which is carried by the slide 64 adjustably mounted on the supporting rod 65 (see Fig. 6). When the clutch is disengaged .the cutter rollers 42 and 43 are idle and they are so driven that they stop in a position such,jfor example, as shown in Fig. 2, as to allow the tape to pass between the cutter rollers and the pressure rollers as is there indicated. However, when the clutch is engaged the cutter rollers are driven and the padding and the backing strip severed at spaced points 31 and 38 and in proper relation to the scores which are also being formed during this single revolution of the cutters. The section 33 of the tape between the cuts 31 and 38 is in this embodiment pulled off by an operator. The tape passes from this station to the winding spool into a guide 66 by which it is guided to the winding drum or spool 61.

The guide 66 serves as a level wind device to distribute the strand upon the spool or drum, it being carried by the lever 69 pivoted at 10 and oscillated by means of the oscillating wheel 1|, the details of this winding device, however, forms no part of our present invention.

To support the feed and pressure belts into gripping relation to the superimposed padding, backing and metal strand We provide guide rollers 68 which are positioned to impart rather abrupt or short curve to the belts at the point the work, as best shown in Fig. 4. This results in a very effective control of the material in its delivery to the pressure belts. The'length of the individual ties isdetermined by the adjustment of the clutch actuating tappet as described, the chain 59 being shortened to produce shorter ties and lengthened to produce longer ties.

The embodiment of our invention illustrated is highly practical, of large capacity and pro.- duces a highly desirable product. We havenot attempted to illustrate other embodiments or adaptations as We believe the disclosure made will enable those skilled in the art to embody or adapt our invention as may be desired.

Having thus described our invention, what we assures claim as new and desire to secure by Letters Patent is:
